To all whom it may] concern:

Be it known that we, Frank HoLnRoon and JOHN J. Do iion, citizens of the United States. residing at Lynn, in' the'county of Essex and State of Massachusetts, havei'nvented certain Improvements in Finishing- Machines, of which the following description, in connection with the accompanying drawings, is a specification; like reference characters on the drawings indicating like parts in the several figures. U

This invention relates] particularly to are chines used in the manufacture of boots and shoes for applying wax, sraia,-b1a1rin 0r other material to a boot or shoe or parts thereof; The materials specifically enu merated are generically termed finishing materials and the machines for applying them are commonly referred to as finishing machines; but this invention is ap-. plicable also to machines for handling other materials capable of being applied to the work in liquid form.

An important object of thisinvention' is to provide means by which the finishing or other material may be applied evenly to the surface of the applying member and by which such material may be handled neatly and economically. w

To this endari impbrtant feature of' t-he invention consists in the provision of means for projecting finishing material onto the applying member, preferablyin the form of a spray. A variety of mechanisms ma be employed for performing this function, but considerations of simplicity and economy have led to the adoption,- in the illustrated embodiment of the invention, of mechanical means for effecting this result. For the same reasons this means is arranged to be manually operated. It is desirable,- of course that the finishing material shall be spread uniformly overthe working face of the applying member in order that this niaterial may be applied evenly to the work. The application ofthe finishing material to the work member in the manner above speci fied greatly facilitates the attainment of this result; but the invention contempiates the provision of additional means for in'sur ing theuniforin distribution of the finish ing material over the surface of the ap ly:

in; member. This means as hcwn eom prises a stationary resilient plate having edge shaped to conform to the contour of the applying member and preferably positioned out of contact with said member but so close thereto that itoperates to spread the finishing material over the surface of the work member as the member moves past it. V

Some compounds used in treating shoes particularly those containing carnauba wax, are solid at ordinary temperatures and can bestbe applied to the work in liquid or semi-liquid conditionr The present invention' includes provision forhandling compounds of thischaracter, delivering them in liquid form to the work member and maintaining them inliquid condition until applied to the work. The invention is directed also to the provision of means for collecting any material thrown from the work member-and to other features that will be hereinafter described and claimed.

1 Referring to the accompanying drawings, Figure 1 is a view in side elevation of the present invention embodied in a heel finishing machine; Fig. 2 an' end elevation of the machine shown in Fig. 1; Fig. 3 is a sectional view through the spraying apparatus, and showing the hood in its inoperative position. r

The applying pad or work member 2, whiclrmay be of any usual or convenient form} issecured fast on a shaft 4 that is mounted for rotation in suitable hearings in the machine frame 6. The work member shown is made up of a number of felt disks clamped between metal collars and usually has a removable cover stretched over its periphery to receive the wear caused by the work. The parts of the mechanism that feedthe Wax or other finishing material on to the work member preferably are supported by the wax holder or receptacle 8. For this reason the holder is provided with a horizontalarm 10 that is slotted at 12 to receive a bolt 1% by whichit is secured rigidly but adjustably to a bracket 16 bolted to the frame 6. It will be evident that by this construction the waX feeding mechanism may be adjusted in a direction parallel to the shaft 4: or may be swung on the bolt let to position itproperly with relation to the work member. The wax holder 8 is in the form of an oblong pan rounded at its corners and provided near its forward end with a depression or pocket 18 which preferably is cylindrical in form. The walls of this pocket are extended upwardly through the wax holder and thus form a cylindrical chamber 20 for the reception of a plunger 22 shaped to fit snugly therein, A small aperture 24 is formed through one wall of the chamber 20 close to the bottom of the holder 8 for the purpose of allowing the finishing material to flow into the pocket 18 below the plunger 22.

The plunger has two holes 26 drilled longitudinally thereof from its lower end nearly to its upper end wherethey are connected by a transversely extending passage 28. Several small discharge openings or ducts 30 are drilled through the upper end of the plunger into the passage 28. The actuating mechanism for the plunger comprises two vertical bolts 32 secured to ears extending from opposite sides of the plunger, these bolts being arranged to slide in vertical holes drilled through bosses 33 formed on opposite sides of the wax receptacle 8. A yoke 34: connects the bolts below the wax holder and is connected to a treadle 36 by a rod 38. The plunger is normally held in its raised position with its lower end just above the opening 24: by means of a lever 40 which is fulcrumed at ll on an arm of the wax holder 8 and has at one end a pin and slot connection 42 with the yoke 3st and at its other end a connection with a spring 4i that is attached to the frame 6.

When the treadle 36 is depressed the plunger 22 will be moved downwardly against the tension of the spring l4: across the opening 24, thus cutting off communication between the chamber 20 and the main body of the wax holder. Further movement of the plunger will force the finishing material confined in said chamber up through the passages 26, 28 and 30 against the applying pad It will be evident that if the discharge openings 80 are very small the finishing material will be forced through them in the form of a spray. Preferably the dimensions of the plunger and the number of openings 30 are made such that this spray will be distributed across the entire face of the pad 2, and since the pad revolves rapidly when in operation, this spray need continue but for a short interval of time in order to coat the entire periphery with finishing material.

In some cases it may be desirable to run the pad at such high speeds that ditficulty will be experienced in driving a spray of finishing material on to it, due to the air currents set up by the movement of the pad. In such cases the delivery passages 30 may be made larger in diameter and the finishing material then will be delivered in small jets or streams that will have sufiicient momentum to carry them through the air currents onto the face of the pad. This arrangement may be desirable for other reasons, as where larger quantities of Wax are required than can be supplied conveniently by spraying.

The holder 8 preferably is provided with one or more partitions 45 extending through the bodyof finishing material. These par titions serve to prevent any movement of the finishing material that might cause it to splash or slop over. Each of these partitions should be apertured near the bottom of the holder to allow the wax to assume the same level in all parts of the holder. As previously stated, the compositions commonly used in treating heels are solid at ordinary temperatures and therefore can best be delivered to the work in molten condition. For this reason the holder 8 is provided with a. clamping device 16 adapted to hold a gas burner 48 in position under the receptacle to heat the finishing material therein. Preferably the flame of this burner is directed against the pocket 18 to insure the thorough heating of the, finishing material in the chamber 20 before it is applied to the work member. The peculiar arrangement of the passages and ducts in the plan ger 22 is of special advantage in handling compounds that must be applied in melted condition, since it avoids the necessity of forcing material through small passages of great length where it might harden. With the arrangement shown a comparatively large body of finishing material is forced at each reciprocation of the plunger'into the passage 28 at the inner ends of the short discharge passages 30. The material, therefore, has very little opportunity to cool off during its discharge from the wax holder. This arrangement also affords a more powerful and uniform spray than could be obtained if the discharge passages were longer.

It is essential in handling finishing materials containing wax that they be kept hot while on the wax applying member. For this purpose the machine shown is provided with a hood 50 which is shaped to partially encircle the work member 2. The hood carries a clamp 52 for holding a gas burner 54 in position to direct a flame against its rearward surface. This hood is pivotally mounted on ears 56 projecting from opposite edges of the receptacle 8 and its weight is so disposed relative to its pivots that it tends to tip back into the position in which it is shown in dotted lines in Fig. 2. In order to hold it in operative relation to the work member 2, the hood is provided with a latch comprising a lever 58 pivoted thereto at 60. The lever carries a screw 62 that is designed to engage the rear face of one of the bosses 33 on the holder 8. When in this position the latch effectually holds the hood 50 in its operative relation to the work memher 2 but when the lever 58 is swung out;

treads wardly into the position indicated in dotted lines in Fig. l the screw 62 is moved away from the bossabove'mentioned and the hood ,may'then drop back into its inoperative position. This arrangement affords conven ient access to the work member in case it is desired to remove or adjust it.

While the spraying mechanism abovedescribed delivers finishing material to substantially the entire surface of the work member 2, it is found desirable to employ additional means for insuring the uniform distribution of this material over the work ing surface of the applying member. This means preferably consists of a plate 64 of resilient material having one end secured to the hood 50 by screws, one of'which is indicated at 66. The plate is curved as indicated in Fig. 2 and has its free edge bent transversely to conform to the contour of the applying member 2. lwo screws 68 are threaded through the rear wall of the hood 50 and bear against the plate 64L to hold it in proper relation to the face of the applying member. lhe adjustment of the screws 68 preferably is such that the edge of the plate does not bear upon the surface of the wheel 2 but is sufliciently close to said surface to engage the film of finishing material with which the tool normally is coated. T his plate therefore causes no additional wear on the work member but acts as a distributing device to catch the finishing material and to spread it over the working face of the applying pad. In case it is found desirable this adjustment obviously can be varied to cause the plate 64% to bear upon the surface of the pad 2.

It may happen that the spray of finish ing material will be thrown against the surface of the workmember with such force that it will spatter; or in case an excess of material is applied to the work member the speed of the latter may be such that some of this material will be thrown off by centrifugal action. lhe plate 6% is so positioned that it catches much of this material and re turns it to the receptacle 8. It is found advantageous also to provide the machine with drip pan 70 having sides to project past the edges of the working face of the pad 2. This pan may conveniently be secured to the upper end of the plunger 22 by a screw 72 where it will be in position to catch finishing material that drips from the surface of the wheel 2 when the latter is stationary or is rotated very slowly and also to catch finishing material that may be thrown from the surface of the wheel by centrifugal force. The material collected by the pan 70 will return to the receptacle 8 by gravity.

"While the invention has been disclosed as embodied in a machine for handling finishing materials, it is obvious that the invention is applicable also to machines for handlingothermaterials and it will therefore be understood that the invention is not limited to use with the particular materials 1' red to in describing the invention.
